DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 635,421, dated October24, 1899.

Application filed May 4, 1899. Serial No. 715,564. (No model.)

To all whom it may concern:

Be it known that I, MORTON G. BUNNELL, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Dumping-Wagons, ofwhich the following is a specification.

My invention relates to a construction of dumping-wagon in which'thebottom of the wagon-body is divided into sections arranged to opendownwardly for the purpose of dumping the load.

Objects of my invention are to provide a construction involvingsimplicity, easy operation, facility for rapidly and effectively dumpingthe load, adaptability for uniform adjustment and for positive andcertain closure at the bottom of the wagon-body regardless ofinequalities in the operating and adjusting devices occasioned by strainand continued use, to improve upon the construction described in LettersPatent of the United States No. 532,785,dated January 22, 1895, and toovercome various disadvantages which in practice have been foundincident to the arrangement described in said patent, and also toprovide a construction involving a higher degree of practicability andefficiency than that disclosed by Letters Patent of the United StatesNo. 17 7,324, in which the bottom of the wagon-body consists of a singleboard or piece suspended by chains hung outside the wagon-body.

To the attainment of the foregoing and other useful ends myinventionconsists in matters hereinafter set forth.

In the accompanying drawings, Figure 1 represents in side elevation adumping-wagon understood to embody the principles of my invention. Fig.2 is a central longitudinal section on a vertical plane through thewagon shown in Fig. 1. Fig; 3 is a top plan View of said wagon. Fig.4 isa transverse section on line 00 0c in Fig. 1.

The wagonbody A, which serves as a receptacle of suitable area forreceiving and carrying the load, can be supported from the front andrear wheels B C in any ordinary or desired way. While such wagon-bodycould be of the ordinary rectangular box shape, it is preferably formedwith inclined front and rear ends a a, somewhat after the style of anoblong hopper. The bottom of the wagonbody is divided longitudinallyinto a couple of sections D, which are hung at points adjacent to theirouter longitudinal edges by short cables or chains or like flexibleconnections E, attached to the bottom sections and to the sides of theWagon-body. These chains while suspending the bottom sections at theirouter edge portions serve as flexible hinge connections between thebottom sections and sides of the Wagon-body. Said chains E are arrangedwithin the Wagon-body and are attached to the bottom sections at pointsa little back of the edges of such sections, 'so as to allow said edgesto abut against the inner Walls of the sides a of the wagon-body whenthe bottom sections are in normal horizontal position, as best shown inFig. 4. With this arrangement the outer longitudinal edges of the bottomsections will bear against the sides of the wagon-body when the bottomsections are permitted to swing downwardly, and when the bottom sectionshave swung downwardly to an extent to hang in vertical planes, as inFig. 4:, their marginal portions, to which the chains E are attached,will lie against the inner walls of the sides of the wagon-body.

By employing chains or like flexible connections in place ofpintle-hinges'the bottom sections will at all times be free to operate,it being obvious that were ordinary hinges employed the pivot or pintlebearings would sooner or later become so rusted and clogged with dirt asto seriously interfere with the free action of the hinges.

The chains E form strong and durable connections between the bottomsections and sides of the wagon-body. Said chains can also be appliedand made of such length that the outer longitudinal edges of the bottomsections D will normally abutagainst the sides of the wagon-body alittle above the lower edges of such sides, whereby should any sag occurby reason of long use the Wagon-body will still be closed at the bottomwhen the bottom sections are in their normal horizontal position. Whenthe bottom sections are permitted to swing down, as in Fig. 4, the loadwill evidently be freely and fully discharged.

The bottom sections can be, and as a matter of further improvement are,operated by chains or cables F, but one chain or cable being necessaryfor each bottom section. As a preferred arrangement the chains E, whichserve to hinge the bottom sections to the sides of the wagon-body, areattached to such bottom sections near the ends of the latter, while theraising and lowering chains F are attached to the bottom sections atpoints midway of the ends of such bottom sections. The chains F passthrough openings a in the sides of the wagon-body, and at such pointsthese chains are carried over or about small antifriction rolls orpulleys, which also serve to properly direct the chains or cables. Forexample, the chains which extend upwardly from points adjacent to theinner edges of the bottom sections first pass overantifriction guiderolls or pulleys Gr, arranged within or adjacent to the openings a inthe sides of the wagon-body, and thence pass about guide rolls orpulleys H, also within or adjacent to said openings, the pulleys G beingarranged upon horizontal axes, while the pulleys H are arranged uponvertical axes. The chains F are extended from the pulleys H forwardly tothe front of the wagon and attached to a transversely-arranged rotarywinding shaft or drum I,mou nted upon the forward end of the wagon-bodyand conveniently arranged below the drivers seat K. Any suitable meansadapted for operating and locking the winding shaft or drum and arrangedwithin convenient reach of the driver can be employed. For example, theshaft can be operated by a lever-handle L, hung loose upon the shaft andcarrying a pawl M, arranged to engage a ratchet N, fixed upon the shaft.ith such arrangement the shaft can be locked by a pawl or dog 0, pivotedon the wagon-body and arranged within easy reach of the driver. Thisarrangement does away with the objectionable presence of a winding-shaftover the receptacle formed by the wagon-body and also does away with theobjectionable feature of a couple of operating-chains to each bottomsection. Hence should either chain F sag or lengthen the bottom sectionto which it is attached can still be drawn into proper position, itbeing obvious that where two operating-chains are attached to one bottomsection undue extension of one of such chains will cause one end of suchbottom section to be drawn up higher than the opposite end when thesection is adjusted for the purpose of closing the wagonbody at itsbottom.

\Vhat I claim as my invention is- 1. A dumping-wagon comprising a coupleof swinging bottom boards hinge-connected with the side-boards at theirouter edges; each board being operated and upheld by a single chainwhich is attached to the board at a point substantially midway betweenits ends, and which is extended upward over a couple of small sheaves orrolls in one of the side-boards and then forward to winding mechanismarranged within reach of the driver.

2. Adumping-wagon having a bottom comprising a couple of swingingsections suspended from opposite sides of the wagon-body by pendentchains or cables arranged within the wagon-body and constituting hingeconnections between the outer longitudinal marginal portions of thebottom sections and the longitudinal sides of the wagon-body, saidpendent chains or cables being of a length to hinge the bottom sectionsat points along their outer marginal edge portions and to maintain suchedge portions in juxtaposition to the sides of the wagon-body; a chainor cable attached to each swinging bottom sec tion between the ends ofthe latter for the purpose of operating the same, and extendingforwardly toward the front end of the wagon; and winding mechanism forsaid operatingchains arranged at the front end of the wagon,substantially as described.

3.
